Dame Diana Rigg, the Sexiest Brit in History, is set to appear on the next season of Doctor Who, the series’ official UK blog has announced. The former star of the British adventure series The Avengers will act opposite her real-life daughter, Tipping the Velvet actress Rachael Stirling, in an episode scripted by Mark Gatiss. This will be the first time Rigg and Stirling have ever shared screen time.

“Character details remain under wraps,” reports the BBC, “but the episode penned by Mark Gatiss will see Dame Diana and Rachael recreate their off-screen relationship on-screen, as they play a mother and daughter with a dark secret.”

Rigg, who has been cast as a “Yorkshire local,” says, “The first time Rachie and I will be working together is on an episode of Doctor Who specially written for us by Mark Gatiss. How lucky is that?”

Stirling adds: “What joy. I am looking forward to the madness of Doctor Who enormously. Mark Gatiss has written a gift of a script and an on-screen relationship between Ma and I that is truly delicious. We have never before worked together because the offers have not been tempting, but when such a funny and original script comes through you know the time has come.”

Head writer and executive producer Steven Moffat says, “Dame Diana Rigg, Rachael Stirling and a Mark Gatiss script — a combination of talents you could only get in Doctor Who! Frankly, I’m terrified already!”

The episode, which will feature Matt Smith as Doctor and Jenna-Louise Coleman as the companion, will air in 2013, with filming set to begin this week (July 2) in Cardiff.
